Wet end Control Systems
|
Corrugating plants need enhanced wet end controls to maximize machine speeds and to optimally manage the wet end. Qualitek has the most advanced and innovative Production Control System. This system optimizes the corrugator by producing high-quality board at the highest possible speeds. It optimizes the wet end logistics of the corrugator through functions such as bridge speed controls, synchronized splicing, roll lineal computations, end of roll splicing and butt roll minimization. Corrugator Production Control System BridgeTek Bridge lineal is maintained at an operator-entered target by adjusting singlefacer speed. Doublebacker speed is changed in the event that speed limits on the singlefacer prevent the bridge from being balanced. Bridge volume is dynamically changed to keep the doublebacker speed steady during a splice sequence. Singlefacer speed is changed to fill the bridge, slowed down to splice speed and returned to cruise speed after the splice. |
SpliceTek On a paper change, splicing of the liners and mediums are synchronized to be within a plant specified splice packet to minimize chop out at the shear. A synchronized splice is automatically initiated on target lineal ly for the last order, or on the running out of a critical roll (to eliminate butt rolls) or as required by the operator. As splices are fired, optimal speed control of the singlefacers and doublefacer are in effect... A data link to the dry end controller automatically obtains order information and handshakes with the dry end to initiate the order change. Optimal speed control for splicing The singlefacer and doublefacer speeds are lowered to their target splice speeds before a liner or medium splice is initiated (manually or automatically). In either event, speeds are adjusted in a programmed sequence to build up the bridge, slowed down to splice speed and ramped up to operating speed after the splice. Page 1 of 3 |
